To all whom it. may concern:

Beit known that I, JOHN` M. R. Fixinnanima subject@` of the King ofEngland, residing at MontreaL-in the Province of Quebec, Canada, have;invented'certain new and useful l:mprovemcnts in Janchor rl`ie Plates,of which't-he following'is a' specification.

rl'his invention relates toa novel' railholding tie platepossessingspecial utility-in facilitating. the accurate laying andseating of rails on ties without the'use, ifldesired, of the usualrail-holding` spikes-orY equivalent fasteners.

Primarily, therefore, the present invention contemplates a novelycombination of features in atie plate responding to the requirementsoftrack as to correctipositionY ing and seatingofthe rail, as wellasfacilitating the convenient'laying andholding of the rail without beingspiked down independently of the tie plate spikes as is now thepractice.

Furthermore, itl is now considered by skilledengineers good practice to'hold'the rail canted or inclined in' track, and to give it aseat on'arail-plate seat crowning in the direction ofthe length of therail, thusbetter enabling the rail to properly absorb and distribute thelloa-'dingstrains- To that end the' present invention provides aipractica-l tie plate combining 'those features'together with the novelmeans for holding a rail to' gauge, as well as preventing displacementfrom its seat, and l'accomplishing thesedesirable results without theuse of rail-holding spikes. i

As is wellknow'n tothose familiar rwith track conditions, there is adecided tendency of rails in either straight orcurved 'sections of trackto roll out or become `tilted outwardly due to thecombination of forcesacting upon the head `of the'frail, thus causing'undesirabledisalinement and spreading ofthe rails. That is to say,4owing to the wheel load acting vertically'and the wheel flangethrustacting horizontally on the head of the rail, there is a`tendencylfo'r the head of the rail to ycant outwardly fronr the gaugeside. Under themostfavorable conditions of'I track, rolling stock, andspeed, there would be very little wheel flange thrust against thel'rail.'Anch if curves could be elevated to meet the requirements of eachtrain, 1f car trucks pivoted freely, .andthe track could be maintainedto a perfect line the rails would be negligible. 'll-lowever, sincethese ideal'conditions` are not entirely practicable, `the lateral wheelfiange thrust `and surface,-the lateral thrust or strain'on f becomes afactor thatmust be taken care of,

thus` making it ldesirable to cant or tip the rails inwardly-so as tobring'y the rail base in a plane approximately at right angles to theresultant of the combined vertical and lateral forces acting on t-herail.

These conditions are recognized in the making of the present invention,which therefore is intended-to,.respond as far as practicable totheideal conditions recited, at the same time' making it possible toestablish a new practice of accurately fitting tie plates'to theties ina shop foi-other place with shop facilities, and afterwards placing the'ties in the road bed, properly alining the tie plates and hooking-inthe rail on the tie plates without the use of spikes or equivalentfastenings'foren'gaging the rail.

A further object of the linvention is to provide a novel constructionoftie plate which lends itself readily to theI application of a railcheck or anti-creeping means, which may or may not be employed if'desired.`

It willbe seenthereforethat' the present invention providesl aconstruction which facilitates the emplacement of a rail 'in track, asWell as providing means for holding they same onto its seat without thenecessity of spikingl to the flanges thereof, and at the same timehaving thef advantages incident to th'e use of atie plate presentin-ganinclined and crowned rail seat, `so distributingthe lateral thrust andthe wheel loads as to firmlymaintain the position of the railfand allowthe latterto adjust itself easilyunde'r the load. vAt the same time theimproved 'construction permits the tiesto be bedded in ytheir usualyhorizontal position.

In its more specific aspectitherefore the p resent t inventioncontemplates af 4novel railh'oldingitieplatecombining novel' structuralfeatures, includ-ing a seat designed yto better permit the Wave motionofthe trail to carry tion and arrangement of parts hereinafter morefully described, illustrated and claimed.

Though the invention is necessarily susceptible of embodiment inmodified forms of construction without departing from the spiritorprinciple of the invention, nevertheless, for the purposes of example,a preferred and practical embodiment of the 1nvention is shown 1n theaccompanying drawings in which- 'Figure l is a plan view of one form ofrail-holding tie plate containing the present invention.

Similar reference characters designate corresponding parts throughoutthe several figures of the drawings.

In carrying the present invention into 'effect it is proposed to providea rail-holding tie plate l of suitable dimensions and having a rail seat2, and a horizontal tie-engaging base 2a, of a suit-able character. Acharacteristic featureof the tie-plate is that the rail. seat 2 isinclined at a predetermined ratio, such as l to 20 or other ratiofigured accurately to obtain a proper canting of the rail, so as tobring the rail base into a plane approximately parallel to the coning ofthe wheel. Furthermore, the inclined rail seat is preferably crownedtransversely of the plate, as shown, the crowning being in the directionof the length ofA the rail, as indicated in Figures 4 and 7, therebyreducing the frictional area of the rail base with its seat andproviding easement from the rail at the edges of the plate so thatbetter freedom is given to the rail in its wave motion.

it the outer side of the rail seat 2 the tie plate body l is providedwith an outer abutmentV shoulder 4, having an upright inner wall 5,while at the opposite side of the rail seat the tie plate is formed withan upwardly projecting inner abutment member 6. ln the suggestedembodiment of the plate shown in Figures l-4, this inner abutment membermay be formed with an inturned hook or holding flange 7 which overhangsthe position of the inner flange of the rail, but this hook or flangemay be omitted, under certain conditions, as hereinafter referred to.rllhe corners of the plate body l or'other portions of the platerelatively remote from the seat 2, and outside of the locations of theouter and inner abutment members 4 and 6, may be provided with theopenings 8 for receiving the screw spikes 9 or their equivalent.

The novel construction of the tie plate l above described permits of thesliding of the rail R laterally onto the seat 2 from the outside of theplate so that the inside flange F of the rail becomes disposed beneaththe overhanging portion 7 of the abutment 6, while the outer base flangeF solidly engages with the upright shoulder 5 of the abutment 4. vWhenthe rail is thus placed in position, it will be apparent that it iseffectually and properly held, because it cannot slide laterally outwarddue to the abutment 5, and its inner flange cannot lift on account ofthe overhanging element 7. However, when it is desired to remove therail for repairs or other reasons, workmen can readily lift the outerflange above the upright face of the abutment 4, and then withdraw therail from its position beneath the hook.

rlhe design of the improved tie-plate lends itself readily to the usetherewith of a suitable rail-check or anti-creeping means. Severaldifferent kinds of such checks can be employed, such for example, asthose shown respectively in the groups of Figures l to 4 and 7 to 9 ofthe drawings. The example of check illustrated in Figures l to 4,consists of a key wedge or equivalent member l0 preferably interposedbetween the edge of one rail flange and the base part of the innerabutment member 6, thus holding the rail firmly against the outer shoulddr of the plate, and providing an effective anti-creeping check or railanchor.

As shown in Figure 5, this check may consist of the key member 10 havinga shank portion il provided with threads l2, the said threads beingmutilated, as indicated at 13, to provide in eect fiat sides for theshank and reducing its width, producing a camming shank member of obllOof the rail and the inside face of the abut menty T withthe head orhandle 14 of the key in an upright position, as shown in dotted lines inFigure t. rllhe said li-ead or handlel may then be struck a blow by atrack man] or other similar tool to ldisplace itirom its uprightpositionto alfiorizontaly position., as also shown by the dotted lines in Figurel andby the full lines in Figure 2. Vllhen the key is thus Jforciblystruc-lcV and rotated on the axis oit its shank, the widest part ormajor diameter or". the shank will be brought into play.y to` force `thethreads or s-rrations thereo'l k into. biting engagement with the edgeof the rail flange and also with the hook. Thus, the rail is eilectivelyheld against longitudinal creeping and at the same time is forced intolirm engagement with the upright face of the shoulder 4 when theanti-creeping means is employed in connection with the tie plate.llllhen it is desired to remove the rail, the anti-Creeper may bereadily withdrawn by prying up the head or handle 14- by means ot anysuitable and ava-ilable tool which will release the engagement of thehook and the rail and permit of the saine being readily removed.

Referring to a desirable and practical embodiment ot the invention shownin Figures 6 to 9 ot the drawings, the inner abutment member G may berecessed as at 20 to receive therein a rail check in the `form of amodern compression spring 2l. This spring preferably is a leafcompression spring, waved throughout its length and disposed against theinner abutment 6 in a direction parallel to the inner rail flange whichis intended to be placed under pressure against said spring. 1n thisapplication of the invention the inturned holding hook or flange 7 ofthe inner abutment shoulder 6 may be omitted, as shown in Figure 9, asthe powerful spring force eX- ertefl by said spring when under tensionwill ordinarily be sufficient to firmly hold the rail against the outerabutment shoulders l on the plate. ln this embodiment, it may bedesirable,y as shown, to have a pair ot spaced outer abutment shouldersll, against which the outer rail flange is held. with an intermediatefulcrum lug 23 bctween, but set back tro-m the said spaced abutments.This 'fulcruin lug permits aclaw bar or other tool tobe convenientlyused in forcing the rail over the abutments la against the holding orcheck spring, as well as facilitating the prying outof the rail from itsseated position. Holes 23 adjacent the ends of the spring 21allordsimilar means to facilitate the seatn'ig or unseat `ing oi thespring.

From the foregoing it will be apparent that the present inventionaiinsto provide a novel rail-holding tie plate for securing the rails inposition without the aidofspikes engaging directly with the rail, thuspermitting the adoption, itV desired, ofthe new practice ot' fitting thetie plates tothe ties ata shop or other place ot assembly with shopconveniences; atter which it will'only be necessary to position the tiesin the road bed, with the tie plates properly aliiied, and then drop'the rail into position by sliding the inner [lange thereof beneath the:hook t3 and permitting the outer flange to drop behind the abutmentshoulder Tfheinvention also permits ot the eftectualzuse` ot' a simpleand practical' type of antiscreeping means, as explained.

VVit-hout. further description it is thought that the features andadvantages of the improvement will be readily apparent to those skilledin the art, and it will of course be understood that changes in theform, proportion and minor details of construction may be resorted towithout departing from the spirit of the yinvention or scope of theappended claims.
